Step 1: Prepare the Space
Take Off Baseboards and Old Flooring
First, take away any baseboards and old flooring to show the subfloor. This gives you a clean, flat area for putting down tile.
Use a pry bar to gently remove the baseboards without breaking the walls. If you have carpet, laminate, or vinyl, cut them into pieces you can handle and get rid of any glue left behind. For old tile, use a hammer and chisel or a floor scraper to lift and take out the tiles and mortar.
Clean the Subfloor Well
Sweep and vacuum the subfloor to get rid of all dust, dirt, and bits. A clean area helps the mortar stick right and keeps your finished floor smooth.
Check for Damage or Wetness
Look at the subfloor for cracks, holes, or bumpy spots. Use a level to find dips or high points.
- Cracks or holes: Fill them with a patching mix.
- Uneven areas: Use a floor leveling mix to make a flat, strong base.
If you’re working over concrete, test for wetness with a moisture meter. High wetness can cause tile or grout problems, so fix any wetness issues before continuing.
Put Down Underlayment or Cement Backer Board (if needed)
Based on your subfloor type:
- Wood subfloors: Put down cement backer board for a strong, water-resistant surface.
- Concrete subfloors: Usually don’t need underlayment, but a crack isolation membrane or waterproofing membrane might be suggested in some situations.
Secure backer board panels as the manufacturer says, using the right screws and leaving the right gaps between panels.
Step 2: Plan Your Tile Layout
Find the Center of the Room and Mark Guidelines
Start by finding the room’s center. Measure the midpoint of each wall and draw chalk lines across the floor. Where these lines meet is where you start placing tiles. This helps keep your tile layout even and balanced.
Choose Your Tile Layout Pattern
For beginners, simple patterns are best:
- Straight Lay (Grid Pattern): Tiles are placed square with the walls, forming neat rows.
- Diagonal (Diamond Pattern): Tiles are set at a 45-degree angle to the walls for a dynamic look—slightly more challenging but doable.
Note: Complex designs like herringbone, chevron, or parquet need advanced skills and aren’t recommended for first-timers.
Dry-Fit Tiles to Check Alignment
Arrange a few rows of tiles without mortar (known as dry-fitting). This helps you:
- Check alignment and spacing.
- See how tiles meet walls, cabinets, or doorways.
- Adjust to avoid thin tile slivers at room edges, which can look awkward and may crack.
Spacing and Grout Lines
Use spacers between tiles during the dry fit to keep grout lines even. Common sizes are 1/8 inch or 3/16 inch, depending on the tile style.
Calculate Tile Quantity (Add 10–15% for Waste)
Measure the room’s square footage (length × width). Then:
- Multiply the total square footage by 1.10 (for simple layouts) or 1.15 (for diagonal or rooms with many cuts) to account for cuts, mistakes, and repairs.
- Order this amount of tile to ensure you have enough for the project.
Step 3: Choose Your Installation Method
For most tile floor projects, especially big ones, thinset mortar is the best way to install tiles. It makes a strong bond between tiles and the floor.
Common Methods:
- Thinset Mortar (Recommended)
This cement-based glue is great for floor tiles. It works well with weight, water, and temperature changes. Most people, both DIYers and pros, use thinset because it’s strong and reliable. - Tile Adhesive (Mastic)
Good for small DIY spaces or wall tiles in dry places. It’s easier to use but not strong enough for most floors or wet places.
Note: For floor tiles, thinset is almost always the best and safest choice.
| Installation Method | Best For | Strength & Durability | DIY Friendliness | Notes |
|---|---|---|---|---|
| Thinset Mortar | Floor tiles, wet areas (bathrooms, kitchens), big spaces | ⭐⭐⭐⭐⭐ (Excellent) | Moderate | Standard for tile floors. Handles water, weight, and movement. |
| Tile Adhesive (Mastic) | Small dry areas, wall tiles | ⭐⭐ (Limited) | Easy | Not for floor tiles or wet areas. Quick to apply but less durable. |
Step 4: Mix Mortar and Apply to Subfloor
Mix the Mortar
Begin by following the instructions on the thinset mortar package to mix it properly. Use a clean bucket and a drill with a mixing paddle to get a smooth mix without lumps. Let it sit for a few minutes, then mix again before using.
Spread the Mortar
Take a notched trowel and spread the mortar evenly on a small part of the floor. Hold the trowel at a 45-degree angle to make ridges. These ridges help the tile stick better and ensure the right thickness for a level tile job.
Work in Small Sections
Only spread mortar on as much floor as you can tile in 10–15 minutes. This stops the mortar from drying before you put down the tiles.
Pro Tip:
For bigger tiles, spread a thin layer of mortar on the back of the tile to help it stick better, especially if the tile is over 12 inches.
Step 5: Lay the First Tiles
Starting right is important for the whole project.
Begin at Your Layout Center Point
Use chalk lines from your planning to start at the room’s center or chosen spot. This helps tiles spread evenly.
Set the First Tile
Put the first tile in the mortar. Press it firmly and twist it a bit to make it stick well.
Use Tile Spacers
Put spacers between tiles to keep spaces even for grout. This makes a neat finish.
Check for Level
After a few tiles, use a level to see if the surface is even. Adjust if needed before the mortar dries.
Pro Tip:
Work in small sections so the mortar stays wet until the tiles are placed!
Step 6: Cutting Tiles to Fit
Cutting tiles correctly is important for a nice, professional look.
Measure and Mark
Use a tape measure to find out the size you need. Make the cutting line clear with a pencil or wax pencil.
Choose the Right Tool
For straight cuts, use a manual tile cutter.
For curved or tricky cuts, use a wet saw or an angle grinder with a diamond blade.
Cut in a Safe Area
Always cut outside or in a place with good airflow to avoid dust. Wear safety glasses and gloves to stay safe.
Pro Tip:
Check your measurements twice before cutting to avoid waste and get a perfect fit!
Step 7: Install Remaining Tiles and Let Mortar Cure
Start by setting the first tiles, then lay the rest one row at a time. Work from your starting point, using spacers to keep grout lines even. Check that tiles are level and adjust if needed to avoid uneven spots.
As you lay tiles, don’t walk on them to prevent movement. Work in small sections so the mortar doesn’t dry before tiles are positioned.
Once all tiles are placed, let the mortar cure for at least 24 hours (or follow the manufacturer’s advice) before grouting. Good curing is key for a strong and lasting tile floor.
Step 8: Apply Grout
After the mortar sets, you can grout between the tiles:
Mix the Grout
Mix the grout as the package says until it feels like smooth peanut butter.Spread Grout Using a Float
Use a rubber float at a 45° angle to spread the grout on the tiles. Push hard so the grout fills all the spaces.Remove Excess Grout
After filling, tilt the float and scrape away extra grout from the tiles.Clean the Tiles with a Damp Sponge
Wait 10 to 15 minutes, then gently clean the tiles with a damp sponge. Rinse often and keep grout in the spaces.Final Buffing
When the grout starts to haze (after 30–60 minutes), use a dry cloth to buff and clear any haze.
Step 9: Clean and Seal the Floor
Remove Grout Haze
Once the grout dries (usually 24 to 48 hours), you might see a hazy film on the tiles. Use a damp sponge or a special cleaner to wipe the tiles gently. Be careful not to touch the grout lines.
Apply Grout Sealer
If the grout maker suggests it, put a sealer on the grout to keep it safe from water, stains, and mold. Use a small brush or a bottle with a roller tip for accuracy. Let the sealer dry completely as per the instructions.
Reinstall Baseboards and Transition Strips
When everything is clean and dry, put back the baseboards and add any needed transition strips between different floors or rooms. This makes your new tile floor look neat and finished.

Pro Tips for a Successful Tile Flooring Installation
Want to achieve great results in your DIY tile project? Remember these tips:
- Save time by organizing tools and tiles beforehand. Keep everything within easy reach.
- Use a good wet saw for clean cuts, especially with porcelain tiles.
- Mix small amounts of mortar and grout. This stops them from drying out too soon.
- Check levels often using a spirit level as you lay tiles.
- Work in small areas. This helps the mortar stay wet until tiles are placed.
- Reduce breakage. Cut tiles slowly and wear safety goggles.
Common Errors to Avoid When Laying Tile Flooring
Even skilled DIYers can make these mistakes:
- Not leveling the subfloor. An uneven subfloor can crack tiles and make lines uneven.
- Not using spacers. Uneven grout lines can look unprofessional.
- Walking on tiles before the mortar sets. This can move tiles and mess up alignment.
- Using too much or too little mortar. This can cause weak adhesion or uneven tiles.
- Not cleaning grout haze right away. Waiting too long can make it hard to remove.
